UCG Ultra with KPN

Hi Everyone,
Hope you all are well.

(apologies this post will be in english, i don't speak dutch language yet but trying)

So i just got a KPN 1G service
I have a UCG Ultra (i might get a unifi express or unifi express 7 in the near future but for now the topology will be like:
kpn ntu / ftu device Ethernet cable to UCG wan port > Orbi in AP Mode.

I checked a few posts and the setup seems simple.

so just verifying that i will set the WAN1 port with :
vlan6
PPOE (any username/password)

I checked the servicetools.kpn.com and once I login it shows me :
Your connection typeGoF
The modem you received from KPN
KPN Box V12 F5359
Your current fiber optic connection point (FTU)FTU_TY01


Any other points/guidance you would like to add here?

Thank you
